Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a cutting tool for machining deep cavities of workpieces. Background Technology

[0002] As the manufacturing industry moves towards higher precision and greater complexity, deep cavity structures are increasingly used in the mechanical field. Deep cavity structures can effectively reduce workpiece weight and optimize spatial layout, but they also place stringent requirements on the machining process. In traditional machining methods, deep cavity machining requires tools with a large length-to-diameter ratio to penetrate deep into the cavity. Due to the narrow space of the deep cavity structure and the long tool overhang, problems such as severe tool wear and uneven cutting force distribution occur during the machining process. This necessitates frequent tool changes to ensure machining accuracy and efficiency.

[0003] Currently, replacing worn-out cutting tools for deep cavity machining is inconvenient and time-consuming. At the same time, precise adjustment of the tool position during machining also faces many difficulties. Even slight deviations can lead to out-of-tolerance machining dimensions, thus affecting the quality of the workpiece. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cutting tool for machining deep cavities of workpieces, thereby solving the problems of inconvenient tool replacement after tool wear and difficulty in accurately adjusting the tool position.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting tool for deep cavity machining of a workpiece, comprising:

[0006] A cylindrical body, wherein a through groove is radially formed on one end of the cylindrical body;

[0007] A pair of transmission plates are slidably disposed in a through groove, and tool holders are disposed opposite each other on the outer sides of the pair of transmission plates, with tool heads bolted to the tool holders;

[0008] A servo motor is fixedly installed inside the cylinder, and an adjustment component is installed inside the cylinder. The servo motor causes a pair of transmission plates to move towards or away from each other through the adjustment component.

[0009] Preferably, the adjustment component includes:

[0010] A rotating plate is rotatably mounted inside the cylinder, and a pair of arc-shaped grooves are provided on the rotating plate;

[0011] A pair of insert rods, the pair of insert rods being disposed on a pair of transmission plates, the pair of insert rods being slidably disposed in a pair of arc-shaped grooves;

[0012] A rotating shaft, one end of which is connected to the center of the rotating plate, and the other end of which is connected to the output shaft of the servo motor.

[0013] Preferably, a partition is provided inside the cylinder, and the servo motor is mounted on the partition with its output shaft passing through the partition.

[0014] Preferably, a bearing is provided between the rotating plate and the inner wall of the cylinder.

[0015] This utility model provides a cutting tool for machining deep cavities of workpieces, which has the following advantages:

[0016] The output shaft of the servo motor drives the rotating shaft to rotate, which in turn drives the rotating plate to rotate. The rotating plate causes a pair of insert rods to move within a pair of arc-shaped grooves, which in turn causes a pair of transmission plates to move in opposite directions. The pair of transmission plates drive a pair of tool holders to move to both sides first, which in turn drives a pair of tool heads to move to both sides, thereby achieving precise control of a pair of tool heads. The tool heads are mounted on the tool holders with bolts and nuts, and the tool heads are replaced when they are severely worn. Attached Figure Description
